PRESSING MACHINE (ROTATING BUCK).

' Application filed September 11, 1925. Serial No. 55,721.

This invention relates to garment pressing machines of the platen type, such as are used for pressing clothing, laundry etc., and has for its object a machine in which the pressing element or platen on which the garment is arranged has a plurality of pressing faces and is rotatably mounted, so that, when a garment larger than said element is once placed on the element with one portion is in posil0 tion to be pressed. After thatportion is pressed and the press opened, the buck can be rotated to bring another face of the press of the pressing element and another portion of the garment into pressing position, thereby greatly facilitating the pressing of garments.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference '1s had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a. side elevation, partly in section. of a machine embodying my invention.

Figure 2 is a front elevation of this machine.

Figure 3 is a detail sectional view of the clutch for controlling the rotation of the buck. Y

Figures 4, 5, 6 and 7 are detail views of parts of the clutch, and the controlling means therefor.

- Figure 8 is an enlarged detail view of a portion of the connection between the operating means for the clutch and the press head, whereby the clutch is operated during the opening of the press head.

This invention comprises generally a press- .4o ing machine having cooperating pressing elements of the platen type, one of which elements is movable toward and from the other,

`and one of which is rotatably mounted Vand.

y means for moving the movable element toward and from the other element.

The pressing elements are preferably a lower buck and a press head movable toward and from the buck, the buck having a plurality of pressing facesand being rotatably mounted on the frame of the machine. It is preferably supported at one end and has its other end free or overhanging.

The head in this embodiment of my invention is actuated by power means, and also che buck is rotated by power means during vaxle or shaft 5 at one end mounted in a bracket 6 supported on the main frame 7 of the machinethe buck being unsupported or free at its other end. The buck is thus rotatably mounted to be moved about an axis eX- tending lengthwise thereof to bring either of the ironing faces 3 or 4 into position opposite the head 2.

The head 2 is formed with a concave face and is carried by a yoke or lever 8 pivoted at 9 between its ends to a standard 10 rising from the frame. The yoke 8 is actuated iny any suitable manner, it being here shown as actuated by power means. The power means forms no 'part of this invention, and further description is thought to be unnecessary. The operating means here shown comprises a power arm 11, pivoted at 12 to the frame 7,

a linkage designated generally 13 between the rear end of the power arm and the rear end of the yoke 8, and a cam or an eccentric or crank pin or roller 14, coacting with the front end of the Apower arm 11 and carried by a shaft 15 which is intermittently actuated by an electric motor 1 6. The. shaft/of the motor is connected to the shaft 15 through suitable gearing and a clutch mechanism located within the housing 17. The .clutch mechanism is normally open and is manually shifted into closed position to clutch the shaft 15 to mechanism which is being constantly driven by the motor 16. The clutch within the housing 17 is thrown into operative position by a manually operated lever 18, and connections 19 operated thereby. In so far as an understanding of the present invention is concerned, it is sufficient to bear in mind that upon the pressing of the lever 18 the clutch within the housing 17 is thrown in and remains in while the shaft 15 and hence the eccentric or roller 14 is making a. half revolution. The clutch is then automaticallythrown to its out position. One half revolution of the shaft closes the press and brings the parts into the position shown in Figure 1. Another half revolution opens the press and brings the roller into a diametrica 1y opposite position to that shown in Figure 1.

The linkage designated generally 13, comprises a link 20 pivoted at 21 to the rear arm of the yoke 8, a link 22 pivoted at 23 to the linkv 20 and to the frame on the same pivot 12 that the arm 11 is mounted on, and a third link 24 pivoted at 25 to the rear end of theV ward closed position by the operator by pulling down on the handle 26. 'This movement brings the links 2O and 24 into nearly, but not quite the position shown in Fig. 1, and also brings the lower end 27'of the link 20 into engagement with the upper end 28 of the link 24. The press is thus preliminarily closed by hand.

Upon the operating of the handle 18 for controlling the application of power to the press head or the rotation of the shaft 15, the front end of thepower arm 11 is depressed .thus lifting the rear end causing the link 24 to push upwardly on the link 20. The link 20 cannot move upwardly rectilinearly, but owing to the link 22 it moves upwardly and forwardly as thev pivot point 23 swings in an arc. In other words, the links 20 and 2-2 form a toggle which is moved into a straight line by the action of the link 24.

The rotatable buck may be turned by hand but preferably is operated automatically by the opening movement of the press. As here illustrated the means for rotating the lower buck comprises an intermittently operated shaft 29 suitably journalled in a housing 30 carried by the frame, a`constantly running driving member 31, a normally open clutch designated generally 32, connecting the driving member 31y and the shaft 29, means operated by the opening movement of the press or yoke 8 to engage the clutch, and automatic means which operates to disengage the clutch. The driving member 31 is here shown (as a worm gear mounted concentric with the shaft 29 and as meshing with the worm 33 mounted on the shaft of a constantly running motor 34, the worm, worm gear and clutch being all located within the housing 30.

The shaft 29 is connected to the shaft 5 of the buck 1 by suitable mechanism here shown as a bevel gear 34a mounted on the shaft 29 and meshing with a bevel gear 35 mounted on one end of an upright shaft 36 suitably carried by the frame of the machine, there being a bevel gear 37 at its upper end which meshes with the bevel gear 38 on the shaft 5. 'Ifhe clutch 32 may be of any suitable form, size and construction, it being here shown as Leeaeee gage the clutch, and means, as a shifter 45,

to engage the clutch against the action of the main spring. Means is also provided for holding the clutch engaged during a cycle of movement of the clutch. rThe shifting member 45 is here shown as carried on a'rock shaft 46 journalled in the housing 30 and :having a lever or arm 47 b means of which b .V

the clutch is operated by the operating means to be presently described, when the clutch section 39 is shifted to the left and moves the pins 4() into the sockets 41 and thus clutches the shaft 29 to the worm wheel 31. ln the event the pins are not in alinement with the holes 41, the springs 43 will compress and when the pins do come into alignment with the holes 41, the springs 43 acting on the pres'- sure ring 42 which in turn acts on shoulders on the pins force the pins into the holes 41. The movement of the clutch section 39 is against the action of main spring 44.

The means for holding in the clutch 32 comprises controlling means, here shown as a ring 50 fixed to the housing concentrically with the shaft 29 and having diametrically opposite notches 51 therein for receiving diametrically opposite rollers or followers 52 on the clutch section 39. Shifting of the clutch section to its in position moves the followers 52 out of the notches 51 so that they will ride upon the high plane faces 53 of the ring and thus hold the clutch in its inl position until the followers again alinev with the notches 51. s

With just one ring 50. thc shaft 29 would make a half revolution, but owing to the reduction gearing between the shaft 29 and the shaft 5 it is necessary that the Ashaft 29 make more than a one-half revolution to cause the buck to make a half revolution and therefore means is provided for closing the notches 51 and again opening the notches after the shaft 29 has made the required number of revolutions. Preferably, the shaft 29 makes one and one-half revolutions to turn the buck a one-half revolution. The means for closing the notches as here shown comprises a rmg 54 rotatably mounted on the ring 50 and having notches 55 arranged to be brought at certain intervals into alinementwith the notches 51, this ring 54 heilig actuated by a gear 56 having its teeth meshing with teeth 57 on the ring 54. The gear 56 is actuated in any suitable manner by the shaft 29 through a gear 29il meshing with a gear 56a mounted on the same shaft (not shown) that the gear 56 is mounted. The ratio of gearing betweenthe gear 56 and the gear ring 54 is such that the notches 51 and 55 come into alinement only after the shaft 29 has made one and one-half revolutions. It will be understood that the followers 52 are wide enough to enter both notches 51 and 55 when they are alined and hence cannot enter the notches of either one of the rings unless the notches are alined with those of the other ring. The construction of the clutch and its controlling means forms no part of my invention.

rIhe means for controlling the throwing in of the clutch, that is, the operating of the lever 47 by the opening movement of the head 3, comprises a link 57 Figs. l and 2, pivoted at its upper end at 58 to the yoke 8 and at its lower end at 59 to a slide 60 movable in a suitable guide 61 and having means for coacting with a lever 6la mounted on a shaft 62 Fig.

2, which through the arm 68 actuates the clutch shifter lever 47. The shaft 62 also has a manually operable lever 65 thereon by means of which the buck can be rotated when the head is open without actuating the head.

In the illustrated embodiment of my invention, the slide 60 is provided with a cam 66 pivoted at 67 thereto, and spring-pressed in one direction by a spring 68, this cam having a cam face 69 coacting with the pin 70 at the outer end of the lever arm 61a. In Fig. 8, the slide is shown as. in an intermediate position. When the press head is down in its position shown in Figs. 1 and 2, the slide 60 is at the lower end of the guide i 61, and the lever 61a in nearly its full line position shown in Fig. 8, with the pin 7 (l above the upper end of the cam surface 69. As the.

head opens and moves clear of the buck 3, the slide 60 'is pulled upwardly in the gui'devGl, moving the cam 66 into engagement with the pin 70 on the lever arm 61a, thus rocking the lever arm 61*1 upwardly as indicated in dotted lines Fig. 8 and actuating the shifting lever 47, to thrust the clutch 32 in The pin 70 moves off the .lower end of the cam surface 69 into the position shown in full lines Fig. 8, as the press head reaches its open position. In Fig. 8, the lever 61a is shown in its position occupied when the press head Vis open and the slide up, and when in this position the clutch 32 is free to be thrownout by the main spring 44 when thenotches 51 and 55 of the rings 50 and 54 are brought into alinement. During the closing of the press and hence during downward movement of the slide 60 the pin -70 slides behind the cam 66 at the left of the cam`66 during the downward movement of the slide 60, and at the end of such downward movement, the camA 66 ratchets under the pin 7 0 so that the pin 70 is in position to engage the cam 'surface 69 during the next upwardmovement of the cam 66. The spring 68 is coiled about the Cshaft 27 and has one end anchored thereto, and its other end anchored at 68* lto the cam 66.

In operation, the operator places a garme-nt on the lower buck, which garmentis wider than the lower buck, the operator pulls `down the press head 2 by hand and applies final pressure by depressing the operating lever 18. When the press has been held closed as long as desired, the operator again depresses the lever 18 whereby the press opens,` the yoke 8 and the head 2 swinging upwardly during such movement and the clutch 82 is operated to connect the shaft 5 of the buck 'l to the driving member 3l, so that, the buck is rotated a half turn during the opening of the press, bringing another ironing surface under another portion of the garment, and such other portion of the garment into pressing position, whereupon the operations are repeated.

It is immaterial Whether the garment sleeves over the lower buck or is a ilat gar` ment wider than the buck. In either case., afterthe garment is yfirst arranged on the buck the pressing operations can be brought about rapidly and during the rot-ation of the buck the garment automatically Varranges itself on the buck.

What I claim is:

1. In a pressing machine, a buck mounted to rotate about an axis extending lengthwise thereof, a head movable toward and from the buck, and the buck having pressing faces on opposite sides thereof and being rotatable about a horizontal axis to bring the faces suc.- cessively into position to coact with the head,
